Go to the grandson

It's the grandson's birthday. Also, in a weird way, the guy slightly older then me is kind of okay-ish. You lean back against the old man groping you and whisper in his ear, "daddy, I need to take care of the birthday boy. thank you." I nibble on his ear for a split second after I finish my little speech. I lift my tiny, soft body off the old man and remove his hands from by breasts and ass.

My eyes connect with the birthday boy. His eager and excited smile is larger then any I have seen in a man. Through the pimples, mismatched clothing and lack of muscles, there is something adorable about him. I slowly take the 5 steps away form the old man and walk towards the 21 year old birthday boy, making sure to never loose eye contact. As I walk, I shake my ass so to keep old horny gramps still happy.

Birthday boy can't help glancing away from my eyes to look at my soft, perky tits. I giggle and say, "It's okay, you can look. In fact, you can touch if you want too." I bend over, showing grampa my ass and thong from under my super short skirt, and lower my breasts down towards birthday boys crotch, still covered by both hands. I bend further over so that my breasts are inches away from his crotch and hands. This further exposes my butt to the old man, hiking it totally up to my waist. I place my tiny, soft hands on top of birthday boys hands and massage them for a moment. I whisper, "I really like you. You can relax. I want you to feel comfortable." I slowly remove both of his hands from his crotch and place them on my breasts. His hands are larger then I though. He immediately begins softly squeezing and twisting them.

Birthday boy moans and begins, whispers, "My name is Michael. I really like you. When I stroke myself to porn, I don't look at women at hot as you because I never thought I'd be touched by someone like you." A bit louder he says, "I wish I could date someone like you in real life." I raise my finger to my mouth and make the "shhh" sign. I lower my hand and brush against the his crotch. Despite his thick jeans, I could feel it pulsing. As i brush my hand against him, I feel the pulse become rapid then wet. I am pretty sure Michael just came in his jeans. I look up at his face. Michael says, "sorry" and runs out.

I turn around and look at the grandfather. He's smiling while going through his wallet. He hands me another $100 bill and says, "good job baby doll." He takes out a pen and paper and writes something down. He hands me the paper and says, "$200 if you go on a proper date with my grandboy." You take the paper and leave the private room.

Later that evening you return home. You take out that paper. It has Michaels phone number as well as his. Apparently his name is Alfred. The note on the bottom says, "$200 for a date with Michael, $1,000 if you stay his place after. Text me your decision by tomorrow morning and if so, reach out to Michael by tomorrow afternoon. P.S. don't tell him about this transaction."

I stare at that note for a few minutes. What do I do?
